Well, I was stomping down the motorway towards Bordeaux. Outside lane at 70mph, cruise control engaged and loss of power fullstop along with a continuous engine light....
Then I had to push between two wagons to pullover. Engine still running, light went off and the pedal started working again??
So that wasn't scary to say the least. I put it back into drive and off I went like it never happened... Drove the rest of the way there and back without the cruise control and not a sausage 🤷
It's definitely new pump time as it's never happened to that extent before😬

In less scary situations, I have had that happen twice over the years. No faults logged and no recurrence for a long time now.

Not nice.

Is it CC related then?
Some quiet roads for testing needed perhaps?

Nah, it's the pump.
Mine idles a little more than 750 and think the actuator could be touching and sticking. I caught a good video on the poo tube about the vw 4cyl version and he was having problems with his. I don't really fancy going in there to do the operation he performs but it could be interesting to find out.
🤔
 
And there constantly a quantity fault logged.. I originally thought it may have been because it's tuned but....

If you take a look at the video there is small particles that can get stuck between the spindle and it's surroundings. 😮

The inside of the pump in the video doesn't look like the inside of the P38 FIP as I remember it. I was told that the "fuel Quantity" problem was likely to be due to a worn end stop for the fuel quantity servo mechanism. A long time ago there was a video of a guy rotating the post that acts as an end stop to cure the problem. The post was clearly notched where the mechanism hit it.
 
Replaced front right wheel sensor after nanocom saying fault abs traction control lights on dash cleared faults but now nanocom saying rear left fault any suggestions be helpful as was ok until I replaced front right

Throttle pot all OK? No wet on it?

+1.

I do remember a small board in the top of it and you can desolder it to take it apart and clean some contacts but I would have to dig through the pictures on an old hard-drive to refeesh my memory as to exactly what.

Taking a trace with the Nanocom when it does it would help.

Wasn't there an issue with the Nanocom WABCO-D module swapping the sides over sometimes? Maybe even an update fixed it at so e stage. MartyUK might have mentioned it.

I want to try swapping the throttle pot on my project car to see if it affects the MIL problem. I have a spare in the scrapper but I don't know if RHD & LHD are different and finding the time at the moment when it's not raining to pull the one out of the scrapper is a problem.

I'd bought these little ball joint linkage kits for a clients height sensor on a crd300 Chrysler there were two in the kit and I only needed one for the job. The second one i fitted to the accelerator pot and peal then drilled a hole closer to the center pin on the pot. It made a real difference to how the engine responds to the pedal movement. A bit more of a modern feeling to the pedal and no, unfortunately the intermittent pump issue has been there for a couple of years now and we'll before the pedal modification. 🤔

It was Marty on the Nanocom forums. I haven't found any mention of a fix from BBS either on the forums or in release notes.

My thought with the throttle pot is a worn track at the point where the pedal is fully up.

It is a good point and I suppose it is the easier of the two to assess between that and the pump. I'm going to check the pump plug and the plug under the header tank for any Corrosion 🤔
